To all whom it may concem:

' Be it known that I Evnnnrr J. Coon, a citizen of the United dtates of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Window-Control Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to window control mechanisms and particularly relates to actuating devices for the sliding windows of motor vehicles.

lhe invention consists in the structural features and arrangement offiparts hereinafter described and illustrated in the accompanying drawings, wherein Figure 1 is a view in interior elevation of an automobile door equipped with .the improved control mechanism;

Figure'Q is a similar view of the mechanism in a modified form Figure 3 is a yertical section on line 3-3 of F igure 1;

Flgure 4 is a perspective view showing the mounting of the actuating element for the mechanism and the latch means for. the

Figure 5' is an enlarged view of a portion of Figure 3. r

In these viewd the reference character 1 designates an automobile door having in its upper portion a window opening '2 and having as a closure'for. said opening a. vertically ,5 slidableglass plate-3 adaptedin lowered position to enter achamber 3? formed in the lower" portion of the door. To the lower edge of the plate 3 there is secured the usual sheet metal channel strip 4 embracing said r plate. 5 is a sheet inetal channel member rigidly depending from the strip 4, the opening of said channel being toward the Yinterior face of the door. 6. is a roller engaging in the channel 5 and carried jointly. by

' the pivotally connectedends-of the two arms 7 and 8. The other ends of said arms are pivoted respectively at 7 and 8 to levers 9 and 10 downwardly extending within the chamber 8 and pivotally connected adjacent their lower ends, fasiindicated at 11. The lever 10 at its upper end carries a roller 12 which engages in a runway formed by a channel bar 13extending substantially along the lower margin of the window opening 2 and terminally rigidly secured to the upnearest adjaceiritv to said levers.

rights of the door 1, said channel bar open ing toward the exterior side of said door. The lever 9 is pivoted atits upper end upon a bracket 14; rigidly depending from the central portion of the runway 13. Upon the mounting pin 15 for the roller 12 there is also mounted a pivotal bell crank member having the upstanding arm 16 carrying a handle 17 and having the arm 16' extending within the channel bar 13 longitudinally thereof. 18 is a V-shaped spring intermedi ately mounted upon the arm 16 and em bracing the transversely bent end 18 of said arm. The ends of said spring diverge somewhat beyond the bent extremity of the arm 16 so as to bear respectively upon the upper and lower flanges of the channel bar 13, thus tending to maintain the arm 16' horizontal. The upper flange of said bar is longitudinally slotted, as indicated at 19, and the arm 16 projects through said slot so as to carry the handle 17 within the window opening 2. A tooth 20 projects downwardly from the bell crank 16, 16 at the juncture of the arms thereof to engage a latch rack 21 formed as an upward projection upon the lower flange of the channel bar 13 (see Figure 4:) 21' is a bar connecting the uprights of the .door 1 within the chamber 3 and passing between the lower portions of the levers 9 and 10 below the pivot 11 thereof and 22 is a coiled spring extending from the pivotally connected ends of said levers to a bracket 23 carried by the end of the bar 21 In the operation of thedescribed device,

when the handle 17 is in its right hand limiting position, as shown in full lines in Figure 1, the glass 3 isfully raised, closing the opening 2. As the! handle 17 is moved to 9&5 the left, the arms 7 and 8 are swung downwardly assuming the dash line position shown in Figure 1 at 7" and 8' when the levers 9 and 10 are adjusted, as indicated at 9 and-10. When the handle 17 has been shifted to a oint substantially midway between the si es of the window opening, the fully lowered position of the closure 3 is established, the corresponding position of theerms 7 and 8 bein -indicated in dotted lines at 7 and 8", the evers 9 and 10 being then disposed as indicated at 9" and 10. The downward an lar movement of the arms 7 and 8 resulting from actuation of the leverlO to the left as disclosed follows me primarily from the fact that the distance of 7 and 8 are swung downwardly from their.

positions 7 and 8 to their fully lowered positions 7", 8".

It will'be noted that the tension of the spring 22 is a minimum when the closure 3 is raised and a maximum in the fully lowcred position of the closure. The movement of the window responsive to the handle is most rapid between the intermediate and fully lowered position of the window and between said position the maximum'countere balancing effect is exerted by the spring 22. Owing to this relation between tensioning of the spring and the varying speed of actuation of the window the pressure required to actuate the closure between the limiting positions is substantially uniform. Further-' more the relativelylarge travelof the handle with respect to the resulting movement of the closure vwhen the latter is adjacent itsraised position gives to the operator a lever age favorable for firmly engaging the weath er strips 24 and 25 which are respectively carried by the lower edge portion of the closure and by the frame of the door. Engagement of the tooth20 with the rack 21 serves to firmly maintain any position of adjustmentof the closure and release of the mechanism is readily accomplished by rocking thebell crank16,'l6 sufiiciently'to raise theitooth 20 j p v v I jc'omb nfation witha; sliding closure, ofa pair vclear of said rack.

h advantages of the described;

construction maybe mentioned the fact that there is avoided any inwardly protruding handle or crank element and also the fact that the arms 7 and 8 and levers 9 and, 10,

which primarily comprise. the mechanism may be cheaply formed of stripped steel by punch press operations and are adapted for connection by punch press riveting.

In the construction shown in Figure 2, the levers 9 and 10 are pivotally connected at their lower ends, instead of projecting below the pivotal connection as in Figure 1. The construction shown in Figure 2 is adapted to be removed upwardly from the chamber 3 after the bar 21- has been unfastened from the uprights of the door The construction shown in Figure 1 permits removal of the mechanism without disturbing the bar 21.

' What I claim as my invention is:- 1. In a window control mechanism, the combination with a sliding closure, of a pair of arms for actuating said closure having pivotally connected ends engaging the closure and slidable thereupon transverse to the sliding movement thereof, pivotal supports for the-other ends of said arms, and means for adjusting said snpports to and'from each other to swing said arms in unison and thereby actuate sliding travel of the closure.

2. In a window control mechanism, the combination with a sliding closure, of a pair of arms having pivotally connected ends engaging said closure and slidable thereupon transversely to the travel thereof,- "a lever mounted to swing transversely to the direction of travel of the closure about a fixed pivot, and a second lever constrained at one end to a travel transverse to that of said closure and pivoted to the first men' tioned lever, said arms being respectively pivoted intermediately to said levers.

3. In a' window control mechanism, the combination with a sliding closure, of a pair ofv pivotally connected arms engaging the closure to actuate the same and slidable upon the closure transversely to its travel, and a pair of. levers respectively pivotally carrying said arms, said arms being angularly actuable substantially in the direction of move-= ment of the closure vby said levers.

4. In a window, control mechanism, 'the combination with a sliding closure, of a pair of pivotally connected arms. engaged with. said closure at their point of'pivotal con- 'nection and having said point s i dable upon the closure transversely to the travel there of, a pair of pivotally connected levers respectively intermediately carrying said arms, a'fixed pivotal support for one of said levers,, and an actuating member carried "by the other lever and constrained'to' a travel transverse .tothatofthef closure.
